Fluorescence thermal quenching of YAG glass-ceramic (YAG-GC) phosphor was evaluated and compared to YAG polycrystal (YAG-PC) and GdYAG glass-ceramic (GdYAG-GC). The fluorescence intensity of the YAG-GC showed smaller temperature dependence than that of GdYAG-GC, although it showed more drastic decrease than that of the YAG-PC.
